Honestly, I can't really tell the difference although I have all three cuts. But I think the Thavar has the least leg opening, then Shioner and Thanaz (Thavar < Shioner < Thanaz). About the rise cuz I feel the same =]

Thavar are slightly tapered with a 14" leg opening. Shioner and thanaz are blocked the same just shioner has a higher rise and different pockets. Shioner and thanaz are straight leg measuring 14" all the way down(based on a 32x32). The rise is basically judged by how high up your waist the jeans go. Hope this helps.
